摘要
马峦山公园高架桥是深圳市南坪快速路三期项目中重要的节点工程,根据现场条件桥梁上部采用了波形钢板-钢管组合梁新型结构,该结构是结合了组合折腹箱梁和组合桁架箱梁的优点所做的一种改良和创新结构形式,具有自重轻、抗震性能好、结构抗裂性和整体性能优异的优点,具备很好的应用前景和研究、推广价值。依托工程开展了模型试验和有限元数值对比分析,其结果可为同类桥梁的设计提供参考。
The Maluan Shan Park Viaduct is an important node project in the third phase of Shenzhen Nanping Expressway. According to the site conditions,the new structure of corrugated steel web-steel pipe composite beam is adopted in the upper part of the bridge. The structure is an improved and innovative structural form combining the advantages of the combined corrugated steel web box girder and the combined truss box girder,and has the advantages of light weight,good seismic performance,structural crack resistance and overall performance. Good application prospects and research and promotion value. Model tests and finite element numerical comparison analysis were carried out based on the project,and the results could provide reference for the design of similar bridges.
